Laptops are bought on the same screen as phones, but you must pick the exact chip, RAM and storage, enter the serial number and use the computer checklist.

Who can do this:
Owner, Store Admin, Manager, Cashier, Appraiser (role defaults; the owner can change them)

Laptops and MacBooks are bought on the same screen as phones. The differences: you must pick the spec that matches the real machine, enter the serial number, and the checklist is the computer one.

Pick the right model and spec

Laptop prices vary a lot with the chip, RAM and storage, so the system makes you choose the spec from the shared catalog. Nobody types free-text model names, and every unit of the same model can be compared on price.

  • Type the model or the shorthand your shop uses, such as "mba m2", "mbp" or the Thai spelling of MacBook Air.

  • You can type the model number from the bottom of the machine or the box.

  • Before choosing a spec, open the machine's own info screen (About This Mac, or System Information on Windows) to read the real chip, RAM and storage.

  1. Open Receive and search for the model in 1. Model and spec.

  2. Tap the model, then choose the spec that matches the real machine under Choose spec.

  3. In 2. Device, enter the serial number. Leave the IMEI empty if the machine has none.

  4. Go through the laptop Checklist, tap only the checks with a problem, then choose the grade.

  5. In Battery, enter the Battery health and the Charge cycles.

  6. Record the seller, enter the price, choose how you pay, then tap Confirm purchase.

The laptop checklist

The checklist depends on the product type. For laptops it covers the screen, keyboard, trackpad, webcam, ports, hinge, SSD health, charging and battery. Three checks are marked Critical:

  • Serial matches the device

  • iCloud / Google / MDM lock removed

  • No BIOS password or firmware lock

If any critical check is set to Faulty/failed, the system warns Don't accept this device, because a locked machine can't be resold. If you save anyway, the device won't become Ready to sell. See Device locked to iCloud or Google: what to do.

What the serial number is for

For devices without an IMEI, the serial number is what stops duplicate purchases. If the serial is still in your stock, the purchase can't be saved. If the machine has passed through your shop before, the system shows its old stock code. See Invalid IMEI or IMEI already in stock: what to do.

The system stores the serial in capitals for you, so lower case is fine.

Frequently asked questions

Contact us

What if the laptop's spec isn't in the catalog?

Send a request from the new-model request page. Don't pick a similar spec instead, because valuations and profit would be compared against the wrong spec.

Should I buy a MacBook enrolled in a company's MDM?

No. The iCloud / Google / MDM unlock check is critical. If it fails, the system warns you not to accept the device, and it won't become ready to sell.
